some of the old books i've read talk
about bear oil as the best gun oil,
patch lube, steel quenching medium, etc.
i've also read about sperm whale oil in
the same fashion. read the same about
bacon grease.
personal belief is that was the best
available or the purest oil some could
get on the frontier.
i've also read that it would rust a firearm
a little less faster than water.
